The  following  work  is  intcndocl  as  a  companion  to  the  "  List 
of  the  Coleoptera  of  North  America,"  by  Dr.  LeConte,  It 
contains  the  descriptions  of  the  new  species  named  by  him  in 
Part  I  of  the  "  List,"  which  embraces  the  families  treated  of  in 
Part  I  of  the  Classification  of  the  Coleoptera  of  North  America. 

The  three  works  having  been  thus  brought  to  the  same  point, 
it  is  the  intention  of  Dr.  LeConte  to  complete  the  series  as  soon 
as  practicable. 

Pages  1— 00  were  published  in  March,  18G3;  pp.  87— 108  in 

April,  1800.

Metby  Portage,  Hudson's  Bay  Territory ;  Mr.  R.  Kennicott. 
This  species  belongs  to  the  same  group  with  C.  repanda,  &c., 
but  differs  from  all  the  species  known  to  rae  by  the  markings. 
The  white  lines  are  all  very  broad,  and  arranged  as  follows :  the 
humeral  lunule  commences  at  the  base,  extends  along  the  margin, 
and  then  runs  obliquely  inwards,  sometimes  so  as  to  touch  the 
angle  of  the  middle  band ;  behind  the  lunule  is  a  white  margin, 
which  extends  to  the  tip,  obtusely  dilated  near  the  tip,  where  it 
represents  the  apical  lunule ;  the  middle  band  arises  perpendicu- 
larly from  the  white  margin,  bends  backM'ards  at  an  obtuse  angle, 
runs  obliquely  nearly  to  the  suture,  and  ends  opposite  the  dilatation 
of  the  white  margin ;  the  hind  part  of  the  band  is  straight  and 
gradually  clavate.  The  elytra  of  the  two  sexes  do  not  differ  ia 
form.  In  one  specimen  the  marginal  line  is  interrupted  in  front 
of  the  apical  lunule,  which  thus  becomes  isolated.

Catskill  Mountains,  New  York  ;  Mr.  Ulke.  Resembles  in  form 
and  appearance  E.  politus  and  E.  Itevigatus,  but  differs  from  both 
by  the  color,  as  well  as  by  the  line  golden  punctures  which  cover 
the  head,  thorax,  margin  and  tip  of  the  elytra,  and  also  by  the 
more  dense  punctures  of  the  breast.

Xova  Scotia ;  Mr.  Ulke.  The  interruption  of  the  3d  and  5tli 
intervals  produce  a  catenated  appearance :  there  are  five  foveae  on 
the  3d,  and  three  on  the  5th  interval ;  the  7th  interval  is  more 
elevated  than  the  adjoining  ones,  but  not  interrupted. 

I  take  great  pleasure  in  dedicating  this  beautiful  species  to  my 
accomplished  friend,  Mr.  Julius  Ulke,  whose  labors  in  the  field 
with  his  brother,  Henry  Ulke,  have  produced  much  advantage  to 
science.

Hudson's  Bay;  Mr.  Ulke.  Allied  to  the  European  Z).  orc</crt, 
but  differs  by  the  thorax  being  more  narrowed  behind,  and  by  the 
elytra  being  less  dilated,  and  almost  parallel.  The  genus  Diachila 
is  not  mentioned  in  the  first  part  of  my  classification,  as  it  was  not 
known  to  be  represented  in  our  fauna  at  the  time  the  work  was 
published.  It  differs  from  Blethisa  by  the  last  joint  of  the  maxil- 
lary palpi  being  elongated  as  in  Elaphrus;  and  from  Elaphrus  by 
the  eyes  being  small,  as  in  Blethisa,  and  the  elytra  striate,  without 
large  foveae.     It  appears  to  me  fully  entitled  to  rank  as  a  distinct

genus,  although  it  is  not  received  us  such  by  many  European  ento- 
mologists. 

I.ORICERA  Latr. 

5.  1..  californica.  Aeneo-nigra  nitida,  thorace  latitudine  breviore,

antice  parce  punctulatis,  externis  fere  obliteratis,  interatiiio  3io  trifo- 
Tuato.     Long.  '32. 

San  Francisco,  California.  Very  nearly  related  to  X.  semi- 
punctata,  but  differs  by  the  much  finer  striae  of  the  elytra  being 
not  punctured,  except  quite  near  to  the  base,  and  by  the  lateral 
margin  of  the  thorax  being  narrower. 

6.  L>.  neoscotica*  Aeneo-nigra  nitida,  thorjice  latitudine  fere  se9';ui 
breviore,  lateribus  rotundatia  refl«*xi3,  angulia  posticia  obtusia  subro-

stitio  3io  trifoveato  ;  tibiia  taraisque  obscure  testaceia.     Long.  '33. 

Nova  Scotia ;  Mr.  Ulke.  Also  related  to  L.  semipnnctata,  but 
differs  by  the  thorax  being  more  transverse,  and  by  the  hind  angles 
being  more  obtuse  and  almost  rounded. 


NEBRIA  Latr. 

T.  N.  lllldsonica.  Nigra  nitida,  thorace  latitudine  duplo  breviore, 
postice  anguatato,  lateribua  marginatia  antice  rotundatia,  postice  oblique 
sinuatis,  angulia  anticia  rotundatia,  poaticia  rectia  vix  prominulis,  linea

Saskatchewan,  Hudson's  Bay  Territory.  Closely  resembles  JV. 
moesta  Lee,  but  differs  by  the  sides  of  the  thorax  being  less  sinu- 
ate, with  the  hind  angles  less  prominent. 

8.  N.  rildis*  Aeneo-nigra,  nitida,  thorace  latitudine  sesqui  breviore,

Methy,  Mr,  Kennicott :  one  specimen.  Resembles  in  form  N. 
Eschscholtzii,  but  differs  by  the  striae  of  the  elytra  being  interrupted 
and  having  large  but  not  deep  punctures;  the  thorax  is  also  less 
narrowed  behind,  and  less  sinuate  on  the  sides.

4  DESCRIPTIONS  OP  NEW  SPECIES. 

A  specimen  from  Washington  Territory,  in  Mr.  Ulke's  collec- 
tion, resembles  the  one  described  above,  except  that  the  sides  of 
the  thorax  behind  are  still  more  feebly  sinuate.  I  am  unwilling,  at 
present,  to  consider  it  as  indicating  another  species. 

CYCHRIJ§  Fabr. 

9.  C.  Tiolaceus.  Saturate  violaceus,  thorace  latitudine  hand  bre- 
viore,  postice  oblique  angustato,  lateribus  late  reflexo-marginatis,  elytris 
ventricosis,  anguste  marginatls,  latitudine  sesqui  longioribus,  striis  con- 
fertis  punctatis.     Long.  '10. 

Mountains  of  Georgia.  This  species  at  first  sight  resembles  C. 
andrewsii,  but  is  immediately  distinguished  by  the  thorax  being 
more  broadly  margined,  and  by  the  elytra  being  more  rounded.  It 
resembles  in  miniature  G.  viduus,  but  the  margin  of  the  elytra, 
especially  towards  the  base,  is  not  so  strongly  reflexed,  and  the 
antennae  are  more  elongated  ;  it  seems  to  be  the  last  term  in  the 
series  of  forms  by  which  C.  unicolor  is  related  to  O.  andrewsii. 

DYSCH1RIV8  Bon. 

10.  D.  hispidus.  Aeneo-niger  nitidus,  clypeo  emarginato  bldentato, 
fronte  transversim  impressa,  thorace  latitudine  breviore,  ovato,  elytris 
convexis  striis  antice  grosse  punctatis,  postice  obliteratis,  interstitiis 
alternis  punctis  setiferis  ininutis  uniseriatis  notatis,  an  tennis  pedibusque 
testaceis,  tibiis  anticis  dente  inferiore  acuto,  superioreque  obsoletissimo 
armatis.     Long.  •12. 

Western  States ;  Mr.  Ulke.  Of  the  same  size  and  shape  as  D. 
setosus,  but  differs  by  the  inner  striae  of  the  elytra  being  distinctly 
impressed,  and  by  the  punctures  being  still  larger. 

CLITIWA  Lath. 

11.  C»  texana.  Elongata,  rufo  ferruginea  nitida,  epistomate  truncate, 
dentibus  utrinque  duobus  parvis  armato,  lobis  oblique  retractis,  impres- 
sionibns  frontalibus  elongatis,  vertice  profunde  sulcato  et  subtiliter  punc-

DESCRIPTIONS  OF  NEW  SPECIES. 


Pennsylvania;  Rev.  D.  Ziog<ler :  Tampico,  Mexico;  Mr.  H. 
Haldeman.  Larger  and  narrower  than  P.  timidiis,  with  the  tho- 
rax less  transverse,  and  more  quadrate,  being  only  a  little  narrower

Ohio  ;  Mr.  Ulke.  In  appearance  this  species  resembles  P.  de-

Nebraska;  Mr.  TJlke.  This  speciec.  is  related  to  P.  adoxus, 
but  differs  from  that  as  from  all  our  otb»r  species  having  no  dorsal 
punctures,  by  the  obtuse  and  rounded  hind  angles  of  the  thorax ; 
in  form  it  is  narrower  than  P.  adoxus,  and  resembles  on  a  large 
scale  P.  longicoUis.  The  tip  of  the  prosternum  is  not  surrounded 
by  a  marginal  line. 

31.  P.  laetulus.  I  propose  this  name  for  the  species  form- 
erly described  by  me  (Journ.  Acad.  Nat.  So.  2d  Ser.  ii.  253),  as 
Pv^ecUus  californicus,  from  which  it  dififcrs  by  the  bright  green 
color,  and  by  the  sides  of  the  thorax  being  distinctly  sinuated 
behind,  and  also  by  the  elytra  being  flatter  and  more  finely  striate. 
Baron  Chaudoir  considers  this  species  as  that  described  by  Dejeao, 
but  I  have  received  from  Count  Mnizech,  a  species  which  corres- 
ponds in  color  and  in  other  characters  with  Dejean*s  description, 
and  which  is  quite  different  as  will  be  seen  by  the  comparison 
above  given.

Louisiana;  Mr.  Ulke.  This  species  is  more  nearly  allied  to  P. 
ohscurus  and  ventralia  than  to  any  other  of  our  native  species  ;  it 
has  like  them  but  five  striae  on  each  elytron,  and  the  scutellar  stria 
is  absent ;  the  2d  dorsal  puncture  is  situated  on  the  2d  stria  as 
usual.  It  differs  from  the  two  species  above  named  by  the  hind 
anglea  of  the  thorax  being  distinct  and  not  at  all  rounded,  but 
this  is  not  sufficient  to  separate  it  from  them  as  a  distiuct  division 
of  the  genus.

Cape  San  Lucas,  Lower  California :  Mr.  Xdntus.  The  third 
joint  of  the  antenna;  is  one-half  longer  than  the  fourth,  as  in  C. 
cumatilis,  from  which  this  species  differs  by  the  form  of  the  thorax 
and  by  the  color.

Canada  and  Western  States.  Much  narrower  and  more  convex

beneath  is  just  as  in  0.  americanus.  A  specimen  from  Canada  is 
still  narrower  and  more  convex,  but  as  there  are  evidences  of  dis- 
tortion about  the  specimen  I  consider  the  difference  as  accidental. 

Mr.  Benj.  D.  Walsh  informs  me  that  this  species  is  found  quite 
frequently  in  the  sloughs  of  the  Mississippi  River,  near  Rock 
Island,  swimming  freely  in  the  water.

Harris  as  A.  agricola ;  what  I  consider  as  Say's  species  has  the 
hind  angles  of  the  thorax  obtuse  but  not  rounded.  The  present 
species  is  readily  known  among  those  with  rounded  angles  by  the 
more  strongly  depressed  and  punctured  sides  of  the  thorax.  The 
elytra  are  distinctly  sinuate  near  the  tip,  and  the  terminal  spur  of 
the  front  tibiae  is  slightly  dilated.*

California,  one  male.  Of  the  same  size  and  shape  as  A.  alter- 
nans,  but  diifers  by  the  much  coarser  punctures ;  as  in  the  other 
species  of  this  section,  having  the  alternate  intervals  of  the  elytra 
punctured,  the  elytra  are  strongly  sinuate  near  the  tip,  but  in  the 
present  species  the  sutural  angle  is  not  rounded.  The  terminal 
spur  of  the  front  tibiae  is  dilated  each  side  into  a  very  distinct 
tooth,  almost  as  in  the  first  and  second  sections  of  the  genus. 


*  The  black  species  of  Anisodactylus  inhabiting  the  eastern  slope  of 
our  territory,  and  belonging  to  the  present  section  of  the  genus,  may  be 
readily  distinguished  by  the  following  table  ;  in  all  of  them  the  terminal 
spur  of  the  front  tibiae  is  but  slightly  dilated  each  side.

One  female,  from  Texas ;  Mr.  Ulke.  This  species  resembles  to 
a  remarkable  degree  Anisodactylus  ellipticus,  but  is  less  convex 
and  less  shining ;  the  first  joint  of  the  front  tarsi  is  longer  than  the 
two  following,  which  are  equal  in  size,  and  about  twice  their  width ; 
the  terminal  spur  of  the  anterior  tibiae  is  broken,  but  is  evidently 
dilated  into  a  large  tooth  on  the  outer  side,  but  whether  there  is 
a  corresponding  tooth  on  the  inner  margin  I  cannot  determine. 
The  first  joint  of  the  front  tarsi  does  not  extend  under  the  second 
as  in  G.  harpaloides. 

The  last  named  species  has  a  very  extensive  range ;  a  female 
was  collected  by  Mr.  Kennicott,  on  the  Ked  River  of  the  North, 
and  a  male  was  given  me  by  Dr.  Schaum,  as  found  in  Louisiana ; 
the  latter  can  in  no  respect  be  separated  from  Anisodactylus ;  the 
middle  and  front  tarsi  are  broadly  dilated,  and  covered  with  a 
dense  brush  of  hairs  beneath,  and  the  first  joint  is  much  narrower 
than  the  others ;  the  terminal  spur  of  the  front  tibiae  is  tricuspid.

Hiulson's  Bay  Territory;  Mr.  Ulke.  A  singular  little  species, 
which  I  was  at  first  inclined  to  class  with  B.  salebratum,  quadru- 
lum,  &c.,  but  the  two  dorsal  punctures  are  placed  upon  the  third 
interval,  and  are  not  connected  with  the  third  stria.  I  have  there- 
fore, for  want  of  a  better  place,  included  it  in  Notaphus,  with 
several  other  species  in  which  the  outer  strite  of  the  elytra  are 
somewhat  obliterated  towards  the  tip.

San  Diego,  California ;  on  the  shores  of  the  ocean.  This 
species  resembles  so  closely  the  figure  given  by  Duval  of  the 
European  P.  nigriventris,  that  it  is  scarcely  necessary  to  add 
anything  to  the  above  description,  to  enable  it  to  be  readily  re- 
cognized. The  spines  of  the  anterior  tibiae  are  very  small,  and 
not  by  any  means  conspicuous.  The  body  beneath  is  finely  and 
densely  punctured,  and  finely  pubescent,  and  rather  darker  colored 
than  the  upper  surface.

known  to  me.  The  dorsal  line  of  the  thorax  is  very  narrow,  and 
a  less  distinctly  defined  one  may  be  observed  on  the  head ;  the 
punctures  of  the  head  and  thorax  are  finer  than  usual,  being 
almost  as  in  S.  tomentosus.  The  golden  spots  of  the  abdomen 
are  very  conspicuous,  and  are  situated  near  the  lateral  margin 
on  the  anterior  portion  of  the  joints ;  similar  but  less  definite 
spots  are  seen  on  the  ventral  segments,  which  are  less  densely  and 
less  finely  punctured  than  the  dorsal  segments.  The  constriction 
of  the  head  is  fringed  with  yellow  hairs  ;  and  similar  yellow  hairs

San  Diego,  California,  under  sea-weed.  This  and  the  follow- 
lowing  species  belong  to  a  division  of  the  genus  which  is  repre- 
sented on  the  Atlantic  coast  only  by  F.  bistriatus  £r.  They  are 
totally  unlike  the  ordinary  species  of  Philonthus  in  appearance, 
but  resemble  Lithocharis.  The  only  species  previously  described 
is  F.  femoralis  Miiklin,  smaller  and  more  slender  than  this,  with 
the  head  finely  punctured. 

Body  dark  blackish-brown,  depressed.  Head  large,  a  little 
longer  than  wide,  sides  parallel  behind  the  eyes,  base  truncate, 
hind  angles  rounded ;  surface  very  coarsely  punctured,  with  a 
broad  smooth  medial  stripe,  which  is  broader  in  front ;  from  the 
punctures  proceed  a  few  short  gray  hairs,  or  bristles.  Antenna) 
one-fourth  longer  than  the  head,  not  much  thickened  externally, 
2d  and  3d  joints  conical,  the  latter  a  little  longer,  following  joints 
nearly  equal,  somewhat  rounded.  Thorax  narrower  than  the 
head,  longer  than  wide,  gradually  narrowed  from  the  front  angles 
to  the  base,  which  as  well  as  the  apex  is  broadly  rounded ;  surface 
not  finely,  but  tolerably  closely  punctured,  with  a  broad  smooth 
dorsal  vitta.  Elytra  longer  and  wider  than  the  thorax,  very  finely 
and  densely  punctured,  clothed  with  short  brown  pubescence ; 
epipleurae  and  a  round  apical  spot  half  way  between  the  suture 
and  margin  dull  testaceous.  Abdomen  finely  and  densely  punc- 
tured and  pubescent,  last  two  joints  inclining  to  testaceous. 
Body  beneath  dark  piceous ;  thighs  sometimes  ferruginous ;  ab- 
domen more  or  less  dark  ferruginous  banded  with  black. 

In  the  male  the  6th  ventral  segment  is  emarginate  behind.

This  insect  might  be  readily  considered  as  a  Pselaphide,  allied  to 
Euplectus,  but  thr,  tarsi  are  four-jointed,  and  the  abdomen  is  flex- 
ile. The  antennas  and  palpi  are  as  in  Eutesthetus,  from  which 
this  genus  differs  principally  by  the  smooth  impunctured  body.

Oculi  parvi,  subtransversi.  Tibiae  liliformes,  baud  spinosse,  calcaribus

This  genus  is  founded  upon  Bitoma  undulata  Mels.,  a  very 
rare  insect  found  in  Pennsylvania.  It  is  closely  allied  to  Bitoma, 
but  differs  by  the  base  of  the  antennae  being  received  in  distinct 
oblique  grooves  beneath  the  eyes.  The  ventral  segments  of  the 
abdomen  are  not  emarginate,  which  is  however  also  the  case  with 
all  the  species  of  Ditoma  known  to  me.

Southern  States;  Dr.  C.  Ziraraermann.  I  take  pleasure  in 
correcting  an  error  I  formerly  committed  in  considering  this  spe- 
cies as  indicating  a  new  genus  of  Colydiini,  to  which  I  gave  the 
name  of  Pleuridium.  The  hind  coxae  are  widely  separated,  and 
although  the  general  form  of  body  is  that  of  Colydiini,  the  genus 
must  be  placed,  as  has  been  properly  done  by  Erichson,  in  Both- 
riderini.  It  differs,  however,  remarkably  from  Bothrideres,  not 
only  in  the  form  of  body,  but  by  the  anterior  coxae  being  con- 
tiguous, and  by  the  first  joint  of  the  tarsi  being  very  long.  The 
structure  of  the  buccal  cavity  is  also  very  different  from  Bothri-

thorax ;  the  eyes  are  small  and  not  prominent ;  the  antennaa  are 
not  longer  than  the  head,  and  the  last  three  joints  are  a  little 
broader.  The  mandibles  are  long,  curved,  slender  and  prominent.

Middle,  Southern  and  Western  States ;  rare.  This  insect  at 
first  sight  resembles  a  small  Haltica  of  the  division  Grepidodera. 
The  genus  has  the  form  and  general  characters  of  Telmatophilus, 
but  diflTers  by  the  9th  joint  of  the  antennae  being  as  wide  as  the 
10th,  thus  forming  a  distinct  three-jointed  club  ;  in  Telmatophi- 
lus the  9th  joint  is  but  little  wider  than  the  8th,  so  that  the  club 
becomes  more  elongate  than  in  Loberus.  The  elytral  striae  also 
afford  a  good  distinguishing  mark  between  the  two  genera.

than  the  lateral  teeth.  The  thorax  is  slightly  pubescent,  and 
there  are  a  few  erect  hairs  towards  the  sides  of  the  body,  but  not 
the  pubescence  that  is  observed  in  Cryptophagus  and  Parameco-

class  in  our  own  species)  resemble  very  closely  the  male  in  form ; 
usually,  however,  the  thorax  is  not  wider  than  the  elytra,  and  the 
latter  are  parallel  on  the  sides,  and  obtusely  rounded  posteriorly  ; 
the  color  of  the  under  surface  is  sometimes  fuscous,  with  the 
sides  of  the  pectus  and  abdomen  testaceous,  but  sometimes  be- 
comes entirely  testaceous.  The  testaceous  margin  and  usual 
bands  of  the  elytra  are  so  dilated  that  the  ground  color  appears 
testaceous,  with  three  irregular  angulated  fuscous  fasciae.

Body  long  ovate,  pale  brown,  fringed  at  the  sides  with  hair. 
Head  rather  longer  than  wide,  coarsely  and  densely  punctured, 
black,  clypeus  rounded,  strongly  margined;  antenna;  pale,  9- 
jointed,  joints  3 — 5  closely  united,  club  longer  than  the  stem. 
Labrum  very  broadly  and  slightly  concave.  Thorax  one-half 
wider  than  long,  considerably  narrowed  in  front,  strongly  rounded 
on  the  sides,  with  a  distinct  marginal  line  in  front ;  surface  sparsely 
pun(«tured,  yellow,  with  a  very  large  transverse  black  spot,  ex- 
tending from  the  apex  nearly  to  the  base,  where  it  is  pointed. 
Elytra  strongly  punctured,  fringed  at  the  sides  with  hairs.  Be- 
neath sparsely  clothed  with  long  hairs,  tibiae  and  tarsi  darker, 
spurs  of  hind  tibiae  both  movable,  obtuse,  claws  armed  with  a 
small  tooth  near  the  base. 

A  species  remarkable  not  only  for  the  color  of  the  thorax,  but 
by  its  anterior  margin  being  thickened,  and  separated  by  a  trans- 
verse impressed  line ;  in  Listrochelus  the  same  marginal  line  is

Middle  States.  Agrees  in  coloration  with  P.  discoideus,  but 
the  dark  spot  of  the  elytra  in  the  male  is  so  large  that  only  a 
narrow  basal  sutural  lateral  and  apical  margin  remains  yellow : 
in  the  female  the  spot  is  not  well  defined  in  front.  The  punctures 
of  the  elytra  are  larger  and  less  dense  ;  but  the  best  distinguish- 
ing character  is  in  the  form  of  the  first  joint  of  the  antennae, 
which  in  P.  discoideus  is  prolonged  and  nearly  acute  at  the  tip, 
but  broadly  rounded  in  the  present  species. 

The  male  (as  in  the  European  species)  is  only  distinguished 
from  the  female  by  the  antennae  being  longer  and  stouter :  no

One  lualc  from  Texas,  in  Mr.  Ulko'a  collection.  The  sculpture 
of  the  thorax  is  peculiar;  it  is  distinctly  and  tolerably  densely 
punctured  at  the  sides  and  before  the  middle,  with  a  very  finely 
punctulate  broad  transverHC  space  extending  from  the  middle  to 
the  base,  and  from  the  dorsal  carina  to  the  depressed  sides. 

The  genus  Pleotomus  was  established  by  me  upon  this  insect, 
(Class.  Col.  N.  America,  184,)  without  giving  a  specific  description. 
It  is  easily  distinguished  from  other  genera  of  Lamjryrini  by  the 
antennae  being  14-joiuted,  about  two-thirds  the  length  of  the  thorax, 
with  uie  Ist  joint  short,  obconical ;  the  2d  scarcely  visible;  the  3d 
to  the  13th  prolonged  externally  and  internally,  so  that  the  an- 
tennae become  bipectinate ;  the  14th  longer  than  the  processes 
of  the  preccc'rig  joint.  The  maxillary  palpi  are  dilated,  with 
the  last  joint  securiform  ;  the  labial  with  the  last  joint  elongated, 
oval,  somewhat  pointed.  The  eyes  are  very  largt ,  and  very 
nearly  approximated  on  the  under  surface  of  the  head,  behind  the 
mouth.  The  7th  ventral  segment  is  broadly  truncate,  or  sub- 
emarginate,  permitting  the  small  conical  8th  joint  to  become 
visible.  The  luminous  segments  (if  any)  are  not  distinguishable, 
owing  perhaps  to  the  general  pale  color  of  the  insect.  The 
pygidium  is  semicircular.  The  last  joint  of  the  tarsi  is  longer 
than  the  preceding. 

This  genus  seems  allied  to  Laviprocera  Lap.,  but  differs  by 
the  greater  number  of  the  joints  of  the  antennae,  and  the  greater 
length  of  the  last  joint  of  the  tarsi. 

MICROPHOTUS  Lkc. 

Antennae  short  and  stout,  scarcely  longer  than  the  head,  2d  joint  nearly 
equal  to  the  1st,  about  as  long  as  wide ;  3d  joint  very  little  longer,  nar- 
rower at  the  base;  4th-9th  gradually  diminishing  in  length;  10th  oval, 
not  longer  than  the  preceding;  11th  very  small,  cylindrical,  truncate  and 
subulate,  as  in  Phausis.  Eyes  immensely  large,  almost  contiguous ;  max- 
illary palpi  with  the  joints  broader  than  lo)ig,  last  one  triangular,  nearly 
acute.  Prothorax  semicircular,  convex  at  the  middle,  widely  flattened 
and  impressed  each  side  ;  finely  scabrous,  without  hyaline  spots.  Elytra 
suddenly  widened  behind  the  base,  rounded  at  the  sides  and  concave 
beneath  the  humeral  elevation,  gradually  narrowed  from  the  middle,  tips 
rounded  and  slightly  dehiscent.  Abdomen  with  the  last  ventral  segment 
prolonged  at  the  middle  and  rounded  at  the  tip  in  all  the  specimens  1  have 
seen  ;  last  dorsal  segment  subtruncate.  Wings  perfect.  Feet  feeble,  com- 
pressed ;  first  and  second  joints  of  tarsi  somewhat  longer ;  4th  joint  short, 
scarcely  lobed ;  5th  joint  slender,  as  long  as  the  two  preceding  united.

90  DESCRIPTIONS  OF  NEW  SPECIES. 

A  very  distinct  genus,  not  only  by  the  form  of  the  antennae  but 
by  the  4th  tarsal  joint  being  not  lobed.  It  agrees  with  Phausis 
in  the  latter  character,  as  well  as  in  the  last  joint  of  the  antennae 
being  small  and  acicular;  but  differs  by  the  antennae  having  one 
joint  less,  and  by  the  thorax  being  destitute  of  hyaline  spots. 

The  under  surface  of  the  body  is  testaceous,  so  that  I  cannot 
ascertain  the  number  of  luminous  ventral  segments,  but  believe 
them  to  be  two,  as  in  Phausis.

by  Dr.  S.  Lewis  and  Mr.  Ulke,  This  species  is  allied  to  P. 
tomentosus,  but  diflfers  by  the  thorax  being  narrower,  less  punc- 
tured, more  deeply  excavated  at  the  middle,  without  a  distinct 
dorsal  impressed  line;  by  the  elytra  being  more  strongly  granu-

Pennsylvania;  Prof.  Haldeman:  Connecticut;  Mr.  Norton. 
A  very  distinct  species,  with  the  portion  of  the  head  behind  the 
eyes  as  long  as  the  front  portion.  The  elytra  are  about  twice  as 
wide  as  the  thorax,  and  of  a  blackish  color,  with  the  basal  fifth, 
and  the  outer  margin  as  far  as  the  middle  reddish-yellow ;  the 
two  colors  shade  imperceptibly  together.  The  antennte  in  one 
specimen  are  nearly  uniform  testaceous,  in  another  they  are 
somewhat  fuscous  externally;  the  joints  are  slender,  the  2d  nnd 
3d  nearly  equal,  and  together  longer  than  the  4th,  which  is  equal

Lake  Superior ;  three  specimens.  A  rather  large  species,  easily 
known  by  the  sexual  characters  :  the  last  dorsal  segment  of  the 
male  is  much  prolonged,  narrow,  and  concave  above,  emarginate 
at  tip,  with  the  lobes  rounded ;  the  penultimate  ventral  segment 
is  very  deeply  and  broadly  emarginate ;  the  last  ventral  prolonged, 
broadly  canaliculate,  produced  behind  into  two  cylindrical  horns, 
ascending  so  as  to  pass  each  side  of  the  prolonged  lost  dorsal 
segment. 

The  females  of  different  species  of  this  genus  resemble  each 
other  in  such  manner  that,  as  already  observed  by  Kiesenwetter, 
it  is  very  difficult  to  distinguish  them :  the  sexual  characters  of 
the  male  are  very  extraordinary,  and  very  easily  recognized  in

punctulate,  and  the  rows  of  punctures  obliterated  near  the  tip. 

3.  G.  pilosella,  agreeing  with  the  last,  except  that  it  is  of 
smaller  size,  with  the  anterior  sinuosity  of  the  thorax  rather  less 
marked,  and  the  surface  more  punctured  and  rugose :  the  rows  of

behind.

One  specimen,  collected  at  "Washington,  D.  C,  and  given  me 
by  Baron  R.  Osten  Sacken.  This  is  the  smallest  species  of  the 
family  Cleridae  known  to  me.  It  is  quite  diflFerent  from  G.  san- 
guineus Say,  by  the  coarser  punctures  of  the  head  and  thorax,  as 
well  as  by  the  narrower  form,  which  is  similar  to  Priocera,  or 
Tarsostenus.  The  anterior  tarsi  are  somewhat  dilated,  while  the 
posterior  ones  are  narrow,  without  distinct  membranous  lobes ; 
I  therefore  consider  it  as  belonging  to  the  division  TJianeroclerus 
Spin.,  although  it  differs  from  that  as  from  all  other  species  of 
Glerus  by  the  hind  angles  of  the  thorax  being  distinct,  though 
obtuse.     The  ungues  are  quite  simple. 

The  lateral  serration  of  the  thorax  is  produced  by  the  punctures 
upon  a  very  obsolete  margin ;  the  sides  of  the  prothorax  beneath 
are  coarsely  punctured,  with  a  smooth  shining  space  near  the 
coxffi :  I  do  not  observe  more  than  four  joints  in  the  hind  tarsi, 
neither  a  short  basal  one,  nor  a  small  fourth  joint  being  visible. 
More  favorable  examination  of  other  specimens  may  indicate  the

propriety  of  placing  it  as  a  new  genus,  near  Tarsostenus ;  the 
antenuaj  have  the  last  three  joints  slightly  enlarged  and  more 
approximate  than  in  Clerus  sanguineus.  The  last  joint  of  the 
labial  palpi  is  very  large  and  dilated ;  the  maxillary  palpi  cannot 
be  seen.

extremely  coarse  silvery  pubescence,  which,  on  the  elytra,  is 
directed  both  longitudinally  and  transversely ;  just  behind  the 
middle  there  is  a  transverse  band  in  which  all  the  hairs  are

at  the  base,  extending  one-third  the  length  along  the  suture.

appearance  G.  vetiista,  but  much  smaller,  and  with  the  punctures 
of  the  thorax  very  large,  umbilicated,  and  not  very  closely  placed. 

The  genus  Cregya  contains  species  placed  with  Pelonium  by 
Spinola,  but  differing  by  the  thorax  being  constricted  behind,  so 
as  to  render  the  sides  sinuate,  and  by  the  anterior  tibiae  not  being 
serrate  externally.  The  antennae  are  11-jointed,  the  first  joint  of 
the  tarsi  is  not  shorter  than  the  second  ;  the  ungues  are  slightly 
dilated  at  the  base  in  C.  vetusta  and  fasciata,  but  very  broadly

of  Enoplium  as  given  by  Duval  and  Kiesenwcttor.  Duval  has 
observed*  that  the  ungues  of  E.  i-punctatum  are  acutely  toothed 
at  the  base,  while  those  of  the  European  species  are  simple.  I 
find  that  they  are  broadly  and  slightly  dilated  at  the  base  in  the 
former,  but  can  hardly  be  called  toothed  :  in  E.  scabripennifi  they 
are  very  feebly  dilated,  while  in  the  Texan  E.  4-notatum  the 
dilatation  is  scarcely  perceptible.

California,  Illinois,  and  Texas.  Differs  from  the  other  species 
in  my  collection  by  the  punctures  of  the  thorax  being  very  distinct, 
not  confluent,  and  not  fine.  The  abdomen  is  rufo-piceous.  The 
sides  of  the  thorax  are  more  finely  serrate  than  in  L.  striatits.  The 
front  coxae  are  more  widely  separated  than  in'the  two  preceding 
species.

Cape  San  liucas,  Lower  California ;  Mr.  Xantus,  This  genus 
differs  from  Triorophus  by  the  superciliary  ridge  being  fine  and 
single  above  the  eyes,  by  the  antennae  being  shorter  aud.  less 
slender,  by  the  last  joint  of  the  maxillary  palpi  being  not  longer 
than  its  width,  by  tJie  eyes  being  larger  and  distinctly  emarginate, 
by  the  thorax  not  being  rounded,  by  the  elytra  being  closely 
applied  to  the  thorax,  with  the  humeral  angles  distinct,  and 
finally  by  the  tarsi  being  pubescent  beneath  and  setose.  The 
large  punctures  of  the  elytra  form  eight  discoidal  and  one 
marginal  series,  and  there  is  a  scutellar  stria  composed  of  three 
or  four  punctures.  The  epistoma  is  trilobed  as  strongly  as  in 
Triorophus,  the  middle  lobe  being  angulated  at  tip  as  in  that 
genus :  the  mentum  is  more  flat  than  in  Triorophus,  being  hex- 
agonal, and  transverse,  with  the  lateral  angles  distinct,  and  the 
front  margin  feebly  emarginate ;  but  the  difference  in  this  respect 
is  neither  obvious  nor  important.

sinuate  each  side,  instead  of  being  slightly  emarginate  in  front, 
and  rounded  each  side.*

*  Lacordaire,  Gen.  Col.  V,  66,  states  that  the  head  of  Eurymetopon  is  not 
oarinate  above  the  eyes.  There  are  no  supraorbital  ridges  as  in  Triorophus, 
separated  from  the  eye,  but  there  is  the  small  acute  fold  in  front  of  the 
eye,  which  disappears  at  its  upper  margin ;  the  same  fold  is  obs'.rved  in 
Triphalus,  Trimytis,  and  Emmenastus,  but  is  wanting  in  Epitragus  and 
Schop-nicus. 

t  I  have  applied  this  generic  name  to  several  species,  which,  while  being 
closely  related  to  Eurymetopon,  differ  in  the  characters  pointed  out  by 
Lacordaire,  Gen.  V,  66 ;  viz.  :  a  shorter  mesosternum,  epistoma  rounded 
in  front,  and  especially  the  anterior  tibise  truncate  at  tip,  not  dilated,  with 
the  outer  angle  not  prolonged.  The  mentum  is  somewhat  emarginate  in 
front,  and  the  ligula  rarely  visible.  Mannerheim,  (Bull.  Moso.  1853, 112,) 
states  that  E.  rugosus  Motsch.,  the  type  of  the  genus,  is  only  a  specimen 
of  Blapstinus  pulverulentns ;  but  whatever  may  be  the  label,  this  view  is 
not  consistent  with  the  generic  description  of  Motschulsky,  upon  which  I 
have  based  the  reference  of  the  species  above  described.  It  seems  to  me 
proper,  therefore,  while  rejecting  E.  rugosus  Motsch.  as  a  doubtful,  or  im- 
perfectly described  species,  to  retain  the  generic  name  for  the  species  to 
which  it  will  apply.

Ulke.  Related  to  P.  hifurcus,  but  much  smaller,  with  the  hind 
angles  of  the  thorax  more  prominent,  the  dorsal  channel  deeper, 
and  the  elytral  costa  diverging  from  the  margin  at  the  humerus, 
instead  of  just  in  front  of  the  middle. 

The  dorsal  costa  terminates  near  the  suture,  about  one-third 
from  the  tip ;  the  marginal  costa  extends  to  within  one-sixth  of 
the  tip.  The  antennae  and  legs  are  very  long  in  the  specimen, 
which  is  a  male.  As  in  P.  hifurcus,  the  anterior  tibiae  are  trun- 
cate at  tip,  with  the  outer  angle  not  prolonged.

shallow,  and  in  the  middle  of  each  is  a  very  short  scale-like  yellow

The  Mexican  Eu.  nitidipennis  belongs  to  group  (a),  and  dififers 
from  the  two  species  above  mentioned  by  the  elytra  not  being  at 
all  costate,  with  shallow  scattered  punctures. 

In  group  (b)  the  anterior  tibiae  are  much  more  dilated  and 
prolonged  than  in  the  other  groups.

Island  of  San  Clemente,  California;  Dr.  J.  G.  Cooper.  Nearly 
as  broad  as  Eu.  reticulatus,  and  like  it  having  the  elytra  distinctly 
margined  at  the  sides  ;  but,  unlike  the  other  species,  the  epiplenras 
occupy  the  whole  of  the  inflexed  portion :  the  marginal  line  runs 
therefore  to  the  extreme  tip,  instead  of  becoming  obsolete  near 
the  tip,  as  in  Eu.  reticulatus,  where  the  margin  is  distinct  from 
the  epipleural  limit.  The  anterior  tibiae  are  considerably  dilated 
and  obliquely  prolonged  at  tip.     The  sculpture  of  the  elytra  is 

datis ;   elytris  punctulatis,  snbstriatis,  versus  marginem  paroe  foveatis. 
Long.  -50 ;  lat.  -27. 

Differs  from  B.  Jloridanus  by  less  convex  form,  less  rounded  sides  of 
thorax,  and  differently  sculptured  elytra.

peculiar ;  small  scattered  granules  are  visible,  equally  distributed  ; 
the  rest  of  the  surface  is  nearly  smooth  at  the  base,  but  gradually 
becomes  granulated,  until  at  the  tip  the  granules  are  quite  dis- 
tinct, though  the  difference  between  them  and  the  larger  scattered 
granules  is  quite  obvious.  The  body  beneath  is  nearly  smooth 
with  a  few  long  yellow  hairs  near  the  edge  of  the  prothorax 
and  on  the  epipleuroe ;  a  few  wrinkles  are  also  seen  near  the 
anterior  coxbb. 

This  species  indicates  a  different  section  of  the  genus  from  any 
heretofore  described. 

The  singular  arrangement  of  the  epipleural  limits  in  the  differ- 
ent sections  of  this  genus  seems  to  demonstrate  the  necessity  of 
uniting  the  Praocini  with  the  Coniontini.  In  this  case  the  tribe 
Branchini  should  be  suppressed,  unless  the  short  gular  fissure  is 
sufficient  to  separate  it.

thorace  angulis  posticis  retrorsum  prodnctis  ;  elytria  abasi  ultra  medium

Cape  San  Lucas,  Lower  California ;  Mr,  Xdntus.  Less  rounded 
in  outline  than  Eu.  reticulatus,  with  the  sides  of  the  elytra  almost 
straight  from  the  base  to  beyond  the  middle,  and  nearly  parallel, 
though  very  slightly  wider  behind.  The  upper  surface  is  dull 
and  entirely  without  sculpture ;  the  under  surface  is  also  dull, 
and  marked  with  only  a  few  wrinkles  on  the  under  part  of  the 
prothorax  near  the  coxa.  The  elytra  are  suddenly  declivous  at 
the  sides,  not  margined  as  in  Eu.  reticulatus,  but  the  epipleurse, 
as  in  that  species,  are  well  defined,  and  suddenly  dilated  at  the 
base.  It  therefore  indicates  a  separate  section  of  the  genus  inter- 
mediate between  Discodemus  and  typical  Eusattus.  The  anterior 
tibiae  are  obliquely  prolonged  at  the  outer  angle,  which  is  rounded 
at  the  tip.

Cape  San  Lucas,  Lower  California ;  many  specimens  collected 
by  Mr.  XAntus.  The  prosternum  is  prolonged  behind  the  eoxte 
into  a  conical  process,  the  inferior  margin  of  which  is  horizontal. 
This  species  is  allied  to  E.  vent ricosa,  hut  differs  by  the  narrower 
form,  by  the  anterior  angles  of  tho  thorax  being  much  more 
prominent  and  acute,  and  by  the  anterior  femora  of  both  sexes 
being  armed  with  H  very  acute  tooth,  while  in  E.  ventricosa  the 
tooth  is  wanting  in  the  female.  The  elytra  of  some  male  speci- 
mens, though  narrower  then  the  female,  are  scarcely  prolonged 
at  tip,  while  in  others  the  prolongation  forms  a  tail,  fully  one- 
fourth  the  length  of  the  elytra.  The  striae  are  strongly  punctured, 
and  quite  distinctly  impressed,  the  interstitial  spaces  feebly  con- 
vex, with  a  few  fine  scattered  punctures. 

Two  females  differ  from  all  the  others  in  having  the  prosternum 
much  less  produced  behind,  and  indeed  very  slightly  prominent : 
I  can  perceive  no  other  difference,  and  therefore  regard  it  as  an 
individual  variation.

Two  specimens,  from  Cape  San  Lucas,  Lower  California,  col-

but  is  a  little  narrower  and  less  rounded  on  the  sides.  The  elytra 
are  more  suddenly  declivous  behind,  less  acute,  and  not  prolonged 
at  tip ;  the  front  thighs  are  very  nlightly  sinuate  beneath,  but  not 
armed  with  a  tooth.  The  prosteruum  is  armed  with  a  small 
prominence  behind  the  coxae.

stronger  sculpture  of  the  elytra.  The  outer  spur  of  the  front 
tibiffi  of  the  male,  as  in  those  species  is  enlarged,  as  long  as  the 
first  three  joints  of  the  tarsi,  and  obtuse  at  tip.  The  under  sur- 
face is  punctured,  and  the  prosternum  is  not  prolonged  behind.

It  seems  to  be  more  nearly  related  to  E.  inculta,  but  the  thorax 
is  more  rounded  on  the  sides,  the  antennse  are  less  elongated  and

One  specimen,  from  California,  given  me  by  Mr.  TJlke ;  another 
remains  in  his  collection.  The  peculiar  sculpture  renders  a  longer 
description  unnecessary.  The  antennae  are  shorter  than  the  head 
and  thorax,  and  the  9th  r-nd  10th  joints  are  somewhat  broader 
than  their  length;  the  11th  joint  is  conical,  and  a  little  broader 
than  its  length.  The  under  surface  is  slightly  shining,  rather 
strongly  but  not  densely  granulated ;  the  prosternum  is  very 
feebly  prominent  behind. 

This  species  differs  from  all  the  others  known  to  me  by  the 
thorax  not  being  margined  at  the  sides :  the  punctures  extend 
upon  the  sides  so  as  to  render  the  outline  erenulate.

New  Mexico ;  collected  by  Mr.  Fendler.  Easily  distinguished 
by  the  more  depressed  form  ;  the  sculpture  of  the  elytra  consists 
of  fine  punctures,  not  arranged  in  rows:  they  are  not  closely 
placed,  and  become,  as  usual,  converted  into  granules  at  the  tip 
and  sides ;  they  gradually  disappear  on  the  inflexed  portion, 
which  is  more  suddenly  and  more  strongly  inflexed  than  in  the 
other  species  of  the  group. 

The  species  of  Eleodes  of  small  size,  with  unarmed  femora,  and

confused  elytral  sculpture,  have  the  middle  lobe  of  the  rr>entuui 
brooder  and  the  lateral  lobes  less  distinct  than  in  the  other 
groups  of  species :  the  miadle  lobe  is  broadly  rounded  in  front, 
and  in  the  present  species  is  slightly  transverse,  with  the  lateral 
lobes  small,  inflexed,  and  scarcely  visible ;  thus  approaching  the 
new  genus  Discogenia,  in  which  they  disappear  entirely. 

E.  clavk'ornis  makes  an  exception  to  the  other  small  species, 
which  requires  it  to  be  separated  as  a  distinct  group :  the  middle 
lobe  of  the  mentum  is  prominent,  elevated,  and  triangular  as  in 
the  larger  species  of  the  genus. 


9I8COOENIA  Lec. 

Eleodes  scabricula  Lec,  and  marginata  Esch.,  differ  from  the 
other  species  which  have  been  referred  to  the  genus,  by  the 
mentum  be'ng  quite  flat,  not  at  all  trilobed,  but  transverse, 
widened  from  the  base  to  the  middle,  then  rounded,  both  at  the 
front  and  sides,  the  lateral  angles  being  also  rounded  at  tip ;  the 
surface  is  punctured,  and  is  foveate  each  side  near  the  lateral 
angle.  The  thorax  is  broader  than  long,  much  rounded  and  finely 
margined  at  the  sides,  with  the  hind  angles  not  prominent ;  it  is 
feebly  emarginate  in  front,  with  the  front  angles  nearly  obtuse. 
The  elytra  are  oval,  not  wider  than  the  prothorax,  pointed  behind, 
considerably  rounded  on  the  sides,  and  without  humeral  angles, 
so  that  they  are  more  distant  from  the  prothorax  than  in  any 
species  of  Eleodes.  The  front  thighs  are  unarmed,  in  the  female, 
slightly  angulated  beneath  in  the  males ;  the  tarsi  are  alike  in 
both  sexes. 

But  two  species  named  above  are  known  to  me.  I  regard  E. 
Jischeri  Mannh.  as  a  large  and  well  developed  form  of  E. 
marginata.

Two  specimens  are  before  me ;  the  anterior  tibisB  are  alike  in 
both,  and  are  straight  and  scarcely  dilated  ;  the  other  characters 
are  those  of  the  genus,  and  as  the  omer  species  do  not  accord  in 
the  form  of  body,  and  front  tibise  among  themselves,  I  regard  the 
distinction  as  merely  specific. 

The  last  three  joints  of  the  antennae  in  Notibius  are  somewhat 
suddenly  wider  than  the  preceding  joints.

A  singular  insect,  having  the  general  appearance  of  certain 
Eleodea,  like  E.  gracilis,  but  with  a  larger  and  longer  head. 
The  sexual  difiference  in  the  anterior  outline  of  the  epistoma  is 
very  remarkable,  and  seems  to  indicate  very  complex  affinities  in 
♦he  direction  of  Helops.  The  slight  compression  of  the  outer 
joints  of  the  antennae  gives  additional  weight  to  this  opinion, 
while  the  manner  of  distribution  of  the  sensitive  pores,  in  small 
rounded  foveae  or  large  punctures,  is  nearly  identical  with  that  seen 
in  Coelocnemis,  Gibdelis,  and  other  forms  allied  to  Upis.

is  dull,  impunctured,  nearly  truncate  in  front,  with  the  apical 
angles  not  prominent,  the  sides  ai'e  rounded,  and  widened  to  a 
little  distance  behind  tho  middle,  then  narrowed  to  the  base, 
which  is  slightly  sinuate  near  the  hind  angles:  these  are  rectangu-

is  seen,  anterior  to  whicL  is  a  very  vague  transverse  impression. 

In  the  male  the  antennaa  are  longer  than  the  head  and  ttiorax  ;

as  wide  as  the  elytra ;  by  the  feet  being  black,  by  the  eyes  more 
strongly  transverse,  and  by  the  antennae  being  shorter  and  more 
thickened  externally.  The  outer  joints  of  ihe  antcnnsB  are  trans- 
verse, and  fully  twice  as  wide  as  their  length.  The  body  beneath 
is  shining  and  finely  but  not  densely  punctured  •  the  under  sur- 
face of  the  prothorax  is  coarsely  punctured. 

Haplandrus  differs  from  Xylopinus,  Upis  and  other  allied 
genera,  not  only  by  the  characters  given  in  the  synoptic  table,* 
but  by  the  prosternum  being  prolonged  behind  the  front  coxa?, 
fitting  into  the  concave  mesosternum.  The  legs  are  sFender  and 
alike  in  both  sexes ;  the  hind  tarsi  are  short,  with  the  first  joint 
as  long  as  the  two  following,  and  the  last  joint  longer  than  the 
other  united.  The  epipleurse  extend  almost  to  the  tip  in  //.

Southern  States ;  not  uncommon  under  bark.  This  insect  re- 
sembles in  form  Uloma  punctulata,  but  is  much  smaller.  It 
difiTers  generically  from  Uloma  by  the  front  tibiae  being  slender 
and  not  serrate,  and  from  Ulosonia  by  the  epipleurae  not  ex- 
tending beyond  the  last  ventral  suture.  The  tarsi  are  clothed 
with  long  coarse  hair  beneath  ;  the  first  joint  of  the  hindmost  pair 
is  scarcely  longer  than  the  2d,  and  the  4th  joint  is  longer  than 
the  three  others  united,  with  the  ungues  large.  The  last  joint 
of  the  maxillary  palpi  is  triangular ;  the  mentum  is  small,  trape- 
zoidal, with  the  a.nterior  angles  bent  inwards.  The  eyes  are  reni- 
form,  transverse,  and  slightly  emarginated  by  the  sides  of  the 
epistoma.  The  1st  joint  of  the  antennse  is  as  long  as,  but  thicker 
than  the  3d,  the  2d  is  shorter  than  the  3d,  which  is  scarcely  longer 
than  the  4th;  the  joints  3-10  are  equal  in  length,  but  gradually 
become  broader,  the  9th  and  10th  being  nearly  twice  as  wide  as 
their  length;  the  11th  is  larger,  rounded.  The  prosternum  is 
flat  behind  the  coxsp,  and  not  prominent ;  the  mesosternum  is 
declivous,  and  concave ;  the  middle  coxab  are  inclosed  by  the 
sternal  pieces,  and  entirely  without  trochantin.

have  placed  in  the  tribe  Ulomini  cannot  be  associated  with 
Diaperini  in  consequence  of  the  epistoma  being  somewhat  pro- 
longed, entirely  concealing  the  membrane  at  the  base  of  the 
labruui,  and  of  the  middle  coxae  being  inclosed  so  as  to  render 
the  trochantin  invisible. 

Duval,  in  separating  the  allies  o{  Diaperis  from  those  of  Uloma, 
has  considered  the  form  of  the  tibiae  as  of  primary  importance ; 
the  close  resemblance  in  all  other  characters  of  value  between 
our  genera  shows  that  character  is  not  to  be  relied  on ;  and 
I  prefer  returning  to  the  one  established  by  Lacordaire,  derived 
from  the  form  of  the  middle  coxae ;  adding  to  it  the  prolonged 
epistoma,  which  conceals  the  clypeus.

An  abundant  species  from  New  York  to  Kansas.  This  species 
(by  description)  diflPers  from  the  European  U.  perroudi  by  the 
thorax  being  narrowed  from  the  base — the  sides  even  near  the  hind 
angles  not  being  parallel. 

The  male  has  the  mentum  somewhat  more  cordiform  than  the 
female,  broadly  concave,  and  not  punctured ;  the  thorax  is  less 
rounded  on  the  sides,  less  narrowed  in  front,  and  has  a  distinct 
but  vague  transverse  impression  near  the  tip. 

It  is  evident  that  the  species  of  Ulovia  are  more  numerous  than 
was  formerly  believed,  but  it  is  quite  possible  that  some  of  the 
species  here  described  may  be  identical  with  those  already  known 
from  distant  parts  of  the  globe.  U.  impressa,  which  has  been 
commonly  considered  as  U.  culinaria,  introduced  in  articles  of 
commerce,  differs  from  the  European  species  described  under  that 
name  by  the  medial  plate  of  the  mentum  being  entirely  glabrous, 
angulated  at  the  sides,  slightly  concave  and  feebly  punctured  at 
the  middle,  sulcate  at  the  sides  in  the  male ;  flatter,  strongly  punc- 
tured, and  more  deeply  sulcate  each  side  in  the  female.

Mississippi  Island,  Gulf  of  Mexico;  collected  b'^  Surgeon 
Thos.  Hewson  Bache,  U.  S.  V.,  and  given  to  me  by  Dr.  S.  Lewis. 
Much  smaller  and  somewhat  narrower  than  P.  testacea,  and  re- 
sembling P.  picipes :  on  comparison  it  diflFors  from  that  species 
by  the  base  of  the  thorax  being  as  wide  as  the  elytra,  so  that  the 
humeral  angles  do  not  project,  and  by  the  sides  of  the  thorax  being 
more  nearly  parallel  behind. 

In  one  specimen  the  color  is  almost  black ;  in  another  the 
thorax  is  dark  testaceous,  the  elytra  black,  with  the  base  and 
sides  pale  testaceous. 

In  P.  picipes  the  first  three  joints  of  the  anterior  tarsi  of  the 
male  are  dilated,  the  2d  and  3d  becoming  strongly  transverse  :  I 
do  not  find  this  character  in  any  other  species  in  my  collection, 
except  P,  globosa.

Atlantic  States,  from  New  York  to  Texas.  I  formerly  regarded 
this  insect  as  a  species  of  Haplandrus,  but  it  differs  from  the 
Tenebrionini  and  Uloinini  by  the  basal  membrane  between  the 
clypeus  and  epistoma  being  visible,  and  in  fact  the  head  resembles 
in  all  respects  the  head  of  Platydema,  except  that  the  eyes  are 
less  prominent ;  the  middle  coxae  are  but  loosely  inclosed  by  the 
episterna,  and  the  trochantin  is  quite  distinct 

The  genus  is  readily  distinguished  from  the  others  of  the  tribe 
by  the  mentura  being  trilobed,  rounded  at  tip,  with  the  lateral 
lobes  short  and  inflexed  as  in  many  Tenebrionini :  the  epipleurae  do 
not  extend  to  the  tip  of  the  elytra;  the  last  joint  of  the  hind  tarsi 
is  longer  than  the  other  three,  and  the  first  is  scarcely  as  long  as 
the  two  following  united ;  the  last  joint  of  the  maxillary  palpi  is 
triangular  and  dilated  as  in  Platydema,  and  the  intercoxal  pro- 
cess of  the  first  ventral  segment  is  triangular  and  rounded  at  tip. 
The  antennae  are  nearly  as  long  as  the  head  and  thorax,  and  are 
moderately  thickened  externally;  the  3d  joint  ie  twice  as  long  as 
the  2d ;  the  4th  and  5th  are  shorter,  but  scarcely  broader  than  the 
3d  ;  the  6th  and  Tth  are  triangular,  the  8th,  9th,  and  10th  trans- 
verse, and  the  11th  rounded,  not  broader  than  the  preceding. 
The  form  of  the  antennae  is  more  that  of  the  Tenebrionini  than 
Diaperini,  but  the  head  is  received  in  the  prothorax  as  far  as  the 
eyes,  as  in  the  latter  tribe.  ,;,     .

The  head  of  the  male,  although  armed  with  two  long  horns,  is 
quite  diflFerent  from  that  of  Hoplocephala :  in  the  latter  the  horns 
are  between  the  eyes,  not  in  contact  with  their  margin,  and  the 
vertex  and  occiput  are  deeply  excavated  at  the  middle  ;  the  an- 
terior margin  of  the  epistoma  is  reflexed  and  bidentate.  In  the 
present  genus  the  horns  rise  abruptly  from  the  inner  margin  of 
the  eyes,  and  there  is  a  large  rounded  excavation  behind  each 
of  them,  the  middle  of  the  vertex  and  occiput  being  convex  ;  the 
epistoma  is  not  margined  or  prominent  in  front,  although  armed 
with  two  small,  distant,  dentiform  tubercles.

Alphitobius,  differs  from  tliem  by  the  epistoma  being  shorter,  less 
prominent  at  the  sides,  by  the  frontal  suture  being  obsolete,  and 
by  the  basal  membrane  of  the  labrum  being  visible.  From  the 
other  genera  of  the  tribe  Hypophlceini,  it  will  be  readily  distin- 
guished by  the  table  given  below.* 

It  seems,  by  the  exposed  pygidium,  to  be  nearly  related  to  the 
European  genera  Ciaphronetis  and  Pygidophorus,  but  differs 
from  tie  latter  by  the  eyes  not  being  approximate  beneath,  and 
from  both  by  the  form  of  the  last  joint  of  the  maxillary  palpi.

New  York,  two  specimens.  This  genus  will  be  readily  recog- 
nized by  the  epistoma  being  broadly  rounded  in  front,  not  separated 
from  the  front  by  a  suture ;  the  basal  membrane  of  the  labrum 
visible ;  eyes  not  emarginate,  frontal  margins  very  short,  nearly 
as  in  Hypophloeus ;  antennae  sknder,  with  the  3d  joint  scarcely 
longer  than  the  2d,  and  the  last  three  joints  about  one-half  wider 
than  the  8th.  The  epipleurae  extend  to  the  tip  of  the  elytra, 
which  are  entirely  destitute  of  striae ;  the  prosternum  is  not 
prominent  behind  the  front  coxae,  which  are  small  and  rounded  ; 
middle  coxae  closely  surrounded  by  the  episterna,  trochantin  not

sutures  deeply  impressed ;  legs  moderate,  tibia  not  dilated,  spurs 
very  minute,  tarsi  hairy  beneath,  last  joint  as  long  as  the  others 
united,  with  large  claws. 

The  total  absence  of  the  frontal  suture  is  a  rare  character,  but 
is  found  in  several  genera  of  this  tribe.  I  also  observe  that  the 
gula  is  longitudinally  impressed  at  the  middle ;  the  mentum  is 
very  small,  and  the  last  joint  of  the  maxillary  palpi  slightly  di- 
lated and  triangular.

B.  Surface  less  shining  ; 

Thorax  densely  and  coai-sely  punctured  ; 
Sides  parallel  behind. 
Sides  narrowed  from  the  Imse  to  the  tip  ; 
Head,  thorax,  and  elytra  uniform  piceous. 
Head  and  thorax  dull  red,  elytra  piceous. 
Thorax  very  finely  and  densely  punctured. 

In  H.  obscurus  and  communis  the  males  differ  from  the  females 
by  the  3d  joint  of  the  antennae  being  but  little  longer  than  the  2d, 
while  in  the  females  the  3d  joint  is  nearly  or  quite  as  long  as  tho

sexes,  but  the  antennoe  are  more  strongly  serrated  from  the  4th 
joint  inclusive,  than  in  the  females.  In  J"  punctati»iiimus  the 
internal  angle  of  the  last  joint  of  the  maxillary  palpi  is  more 
rounded  than  in  any  of  the  other  species.

Cistela  quadriatriata  Coufeb,  Canadian  Natnraliat,  Feb.  1865,  p.  62. 

Lake  Superior,  Canada,  New  York,  Georgia,  Missouri.  A 
widely  diflFused  and  not  uncommon  species,  having  the  upper 
surface  nearly  as  finely  punctured  as  Cistela  sericea,  from  which 
it  is  at  once  distinguished  by  the  more  broadly  triangular,  sub- 
cultriform  last  joint  of  the  maxillary  palpi. 

It  is  with  some  hesitation  that  I  refer  this  species  to  Isomira, 
the  outer  side  of  the  last  joint  of  the  maxillary  palpi  being  in  /. 
antennata  twice  as  long  as  the  apical  side,  while  in  our  species 
the  difference  in  length  is  not  very  great.  I  do  not  observe  a 
complete  uniformity  in  the  form  of  the  part  in  question  in  those 
genera  of  which  I  have  examined  several  species,  and  therefore 
cannot  consider  the  difference  as  sufficient  to  warrant  me  in  pro- 
posing a  new  generic  name. 

In  one  specimen,  from  New  York,  the  inner  side  of  the  last 
joint  of  the  maxillary  palpi  is  distinctly  bisinuate,  but  I  observe 
no  other  character,  except  that  the  head  and  thorax  are  black, 
and  the  elytra  paler  and  more  finely  punctulate  than  in  the  other 
specimens  ;  I  have  mentioned  it  in  the  List  as  /.  veluiina.

One  specimen  (female)  given  me  by  Mr.  Andrew  Murray, 
probably  from  Florida.  I  am  not  entirely  satisfied  with  the 
reference  of  the  species  to  the  present  genus.  The  tip  of  the  man- 
dibles is  simple,  slightly  rounded,  and  not  emarginate ;  the  last 
joint  of  the  maxillary  palpi  is  elongate  triangular,  with  the  apical 
and  basal  sides  equal,  the  outer  lobe  of  the  maxillae  is  elongate 
with  parallel  sides ;  the  antenMae  are  slender,  about  one-half  the 
length  of  the  body,  with  the  3d  joint  a  little  shorter  than  the  4th. 
The  lateral  margin  of  the  prothorax  reaches  the  tip  ;  the  anterior 
coxse  are  separated  by  the  prosternura.  The  tarsi  are  simple, 
not  longer  than  the  tibiae,  and  the  ungues  have  from  6-8  teeth  ; 
the  posterior  portion  of  the  hind  coxae  is  slightly  convex,  and 
does  not  terminate  in  a  sharp  edge.  The  6th  ventral  segment  is 
slightly  visible,  and  the  5th  is  marked  with  a  transverse  oval  ex- 
cavation near  the  tip.     Tl"*  epipleurae  extend  nearly  to  the  tip. 

The  family  Cistelidae  seeras  to  need  a  thorough  revision,  in 
order  that  by  comparing  the  species  from  different  countries  the 
limits  of  the  genera  may  be  properly  defined,  and  their  systematic 
relations  recognized.

This  insect  resembles  in  appearance  Stereojjalpus  mellyi,  but  is 
larger  and  rather  less  slender.  It  differs  generically  in  the  form 
of  the  last  joint  of  the  maxillary  palpi,  which  is  neither  broadly 
securiform  as  in  Eurygenius,  nor  elongate  and  cultriform  as  in 
Stereopalpus,  but  subtriangular,  elongate,  with  the  apical  and 
basal  sides  nearly  equal,  and  the  inner  angle  very  obtuse ;  the 
antennae  differ  from  those  of  the  two  genera  named  by  the  last 
joint  being  much  elongated,  as  in  Statira,  in  the  two  specimens 
before  me  equal  in  length  to  the  four  preceding  united.  The 
sculpture  of  the  head  and  prothorax  is  peculiar,  con.sisting  of 
slightly  elevated  umbilicated  granules.  The  e^'cs,  as  in  Stereo- 
palpus, are  subtruncate  and  scarcely  emarginate  in  front,  and  the 
claws  scarcely  dilated  at  base.  A  longer  generic  description  is 
unnecessary,  as  the  other  characters  are  the  same  as  in  the  two 
allied  genera.

8CRAPTIA  Latb. 
On  examining  the  species  of  SorapHa  in  my  collection,  I  find 
the  differences  in  the  maxillary  palpi  and  hind  tarsi  are  such  as 
to  indicate  three  genera,  as  follows  :  The  last  joint  of  the  labial 
palpi  in  all  three  is  very  transverse,  with  the  apical  side  longer 
than  the  others,  and  the  prosternal  sutures  are  not  distinct.

Penultimate  joint  of  hind  tarsi  not  lobed. 
Last  joint  of  maxillary  palpi  elongate,  onltriform. 


scraptia. 

Allopoda. 

Canifa. 


To  the  first  genua  belongs  Orchesia  sericea  Mels,  The  an- 
tennae are  about  two-thirds  as  long  as  the  body,  not  very  slender, 
with  the  3d  joint  but  slightly  longer  than  the  2d,  and  the  two 
united  are  not  longer  than  the  4th.  The  last  joint  of  the  maxil- 
lary palpi  is  large,  triangular,  about  one-half  longer  than  wide, 
the  outer  side  broadly  curved,  the  apical  and  internal  sides  meet- 
ing at  a  right  angle,  which  is  quite  considerably  rounded,  the 
inner  or  basal  side  about  one-third  shorter  than  the  apical.  The 
penultimate  joint  of  all  the  tarsi  is  cordate,  and  somewhat  lobed, 
and  the  first  joint  of  the  hind  tarsi  is  twice  as  long  as  the  others 
united  in  our  species,  and  but  little  longer  than  the  others  united 
in  the  European  S.  fusca. 

To  Allopoda  belongs  Scraptia  lutea  Hald.,  which  I  have,  by 
the  confusion  of  types  sent  to  me,  erroneously  considered  (Proc. 
Acad.  Nat.  Sci.  VII,  219)  as  the  same  with  S.  pallipes  Mels. 
The  antennae  are  about  half  as  long  as  the  body,  the  2d  joint 
half  as  long  as  the  3d,  which  is  not  shorter  tiian  the  4th.  The 
last  joint  of  the  maxillary  palpi  is  about  one-half  longer  than 
wide,  Bubtriangular,  with  the  internal  angle  more  rounded  than 
in  the  preceding  genus,  and  the  tip  more  acute.  The  penultimate 
joint  of  the  front  and  middle  tarsi  is  cordate,  but  that  of  the  hind 
tarsi  is  slender,  not  at  all  dilated,  and  two-thirds  the  length  of 
the  preceding ;  the  first  joint  of  the  hind  tarsi  is  shorter  than  the 
other  three  unite  J. 

The  third  genus  Canifa  contains  Scraptia  plagiata  Mels.,  S. 
jnisiUa  Hald.,  and  S.  pallipes  Mels.  The  antennae  are  a  little 
more  than  half  the  length  of  the  body ;  the  2d  and  3d  joints  are 
small,  equal,  and  the  3d  is  as  long  as  both  united.  The  last  joint 
of  the  maxillary  palpi  is  cultriform,  fully  twice  as  long  as  its

width,  with  the  apical  side  a  little  shorter  than  the  outer  side, 
aiid  twice  as  long  as  the  internal  side  which  becomes  basal,  and 
meets  the  apical  side  almost  at  right  angles.  The  penultimate 
joint  of  all  the  tarsi  is  cordate  and  somewhat  lobcd,  and  the  first 
joint  of  the  hind  tarsi  is  nearly  twice  as  long  as  the  others  united. 
Allopoda  may  be  distinguished  from  Anas^pia  and  its  allies, 
which  have  similar  maxillary  palpi  and  hind  tarsi,  by  the  last 
joint  of  the  labial  palpi  being  transverse  and  securiform — the 
antennae  not  being  thickened  externally — by  the  anterior  tro- 
chantin  being  distinct,  and  by  the  different  form  of  the  hind  coxae, 
which  do  not  conform  to  the  ventral  surface,  but  are  raised  from  it.

One  specimen,  from  Louisiana,  given  me  by  Mr.  Guex.  The 
dark  markings  of  the  elytra  are  narrow  spots,  one  of  which  com- 
mences at  the  Bcutellum  and  becoming  very  narrow  runs  along 
the  suture,  another  commences  at  the  humerus  and  runs  obliquely 
for  more  than  one-third  tho  length :  near  its  end  and  between  it 
and  the  subsatural  line  is  a  small  spot ;  the  other  spots  form  a 
transverse  undulated  band  behind  the  middle,  and  a  subapical 
blotch  on  each  elytron.* 

The  genus  is  evidently  allied  to  Melandrya,  but  the  fiseure  of 
the  anterior  coxal  cavities  is  narrower,  and  the  trochantin  smaller, 
though  quite  visible ;  the  clypeal  suture  is  less  distinct.  The 
maxillary  palpi  are  moderate  in  length,  the  2d  and  3d  joints  not 
dilated,  the  4th  securiform,  with  the  outer  side  not  much  longer 
than  each  of  the  others,  which  are  nearly  equal.  The  antennae 
are  moderately  slender,  with  the  2d  joint  short,  the  3d  not  much 
longer  than  the  4th  :  the  tip  of  the  last  joint  is  testaceous.  The 
lateral  margin  of  the  prothorax  is  acute  behind,  and  entirely

Pennsylvania;  rare.  The  genus  Anisoxya  is  easily  distin- 
guished by  the  spurs  of  the  middle  tibiae  being  larger  than  those 
of  the  hind  tibiae,  and  unequal ;  the  larger  of  the  two  is  nearly 
one-half  the  length  of  the  first  tarsal  joint.  The  antennae  ai*e 
scarcely  longer  than  the  head  and  thorax,  with  the  3d  joint  not 
longer  than  the  2d,  4th-10th  equal  in  length  to  the  3d,  nearly 
square,  11th  one-half  longer,  oval.  The  sculpture  is  peculiar, 
consisting  of  fine  impressed  lines  having  a  transverse  direction 
and  connected  together,  producing  a  somewhat  squamous  appear- 
ance. 

I  perceive  no  trace  of  the  two  posterioi  oblique  impressions

A  genus  containing  two  small  species,  apparently  allied  to  the 
European  Carida,  but  differing  by  the  emarginnte  eyes,  and 
slender  front  tarsi.     The  characters  as  above  detailed  agree  with

those  of  Dryala  Muls.  (Col.  France,  Barbipalpcs,  58,)  but  the 
prothorax  is  not  bifoveate  at  base,  and  the  eyes  are  less  emargi- 
nate.  The  genus  Dryala  has  not  been  adopted,  because  the  type 
of  it,  Uallomenus  fuscus,  on  examination  by  Schaum,  Redten- 
bacher,  and  DuVal,  was  found  to  have  the  anterior  coxae  separated 
by  the  prosternum,  as  in  the  other  species  of  HallomenuH.  The 
anterior  coxae,  in  the  two  species  described  below,  are  prominent, 
conical,  and  contiguous,  their  cavities  have  a  very  minute  ex- 
ternal JSssure,  and  the  lateral  sutures  of  the  prosternum  are 
obliterated,  in  which  respect  it  agrees  with  the  genera  of  the  tribe 
Scraptiini.  The  characters  are  therefore  anomalous,  and  I  am 
not  certain  that  I  have  assigned  to  the  genus  the  best  position. 

In  the  Classification  of  North  American  Coleoptera  I  incor- 
rectly referred  these  two  species  to  Trotomma,  a  European  genus 
allied  to  Scraptia,  and  like  it  having  the  head  strongly  constricted 
behind  the  eyes  forming  a  small  neck,  which  is  received  into  the 
prothorax.

M.  dimidiata,  in  form  and  sculpture.  The  scutellar  lobe  is 
rounded  at  tip,  and  suddenly  elevated  near  the  tip  into  a  short 
horn,  which  is  truncate  or  feebly  emarginate  at  its  apex.*

Middle  States.  I  owe  to  Mr.  J.  H.  B.  Bland  the  privilege  of  examining 
six  females  of  thia  species.  It  differs  from  M.  Jlaripennis  chiefly  in  color  ; 
the  posterior  half  of  each  elytron  is  black,  but  the  line  of  demarcation  is 
an  angle  directed  forwar(!a.  ao  tliat  at  the  suture  and  side  margin  the  pale

One  male  apecimen,  from  Philadelphia,  in  the  collection  of. Mr.  Bland. 
This  sp«:  -ies  seemp  to  bear  the  same  relation  to  M.  dimidiata  that  M.Jlavi- 
pennis  does  to  the  preceding.  It  differs  merely  in  color  ;  the  antennae  are 
testaceous,  and  the  elytra  margined  with  l:lack  behind  the  middle,  and  at 
the  tip,  the  black  of  the  latter  extending  for  about  one-fifth  of  the  length. 

GerstsBcker  has  described  (Mon.  Bhipiphoridum,  21)  both  sexes  of  M. 
dimidiata  aa  having  the  antonnn  black  with  the  base  testaceous,  and  it 
is  solely  in  deference  to  this  observation  that  I  have  described  the  two 
species  in  this  note.  Otherwise,  I  would  be  tempted  to  regard  M.  abdomi- 
nalis as  the  female  of  M.  Jlavipennis,  and  M.  marginalia  as  the  male  of 
M.  dimidiata.

Differs  from  R.  limbatus  by  the  smaller  size,  different  color,  and 
more  finely  punctured  tburax;  the  posterior  lobe  is  loss  rounded 
at  tip  than  in  that  species.

One  female  from  Oregon,  and  another  from  Montana.  This 
species  is  closely  allied  to  M.  rugipennis,  and,  as  in  that  species, 
the  thorax  is  destitute  of  impressions ;  but  the  punctures  of  the  liead 
and  thorax  are  more  numerous,  and  less  unequally  distributed, 
and  the  dorsal  segments  of  the  abdomen  are  more  finely  rugose. 

The  male,  when  discovered,  will  be  found  to  have  the  5th,  6th, 
and  7th  joints  of  the  antennae  dilated,  as  in  M,  rwjipennis ;  the 
8th  and  9th  joints  of  the  female  are  about  as  long  as  their  width, 
the  10th  is  one-third  longer.

Three  females  from  Nebraska,  near  the  Rocky  Mountains. 
Differs  from  the  preceding  by  the  head  and  thorax  being  still 
more  coarsely  punctured,  the  latter  channelled,  with  the  basal 
margin  strongly  depressed,  and  the  dorsal  segments  of  the  abdo- 
men much  more  finely  rugose.  The  8th,  9th,  and  10th  joints  of 
the  antennae  are  nearly  equal  in  size. 

M.  afer  differs  from  this  species  by  the  color  being  black,  with- 
out any  bluish  tint,  and  by  the  dorsal  segments  being  strongly 
rugose,  as  in  M.  montanus.

coarsely  punctured,  the  latter  more  narrowed  behind,  with  the 
basal  margin  not  depressed ;  the  rugosities  of  the  elytra  are  more 
coarse,  and  those  of  the  dorsal  segments  more  punctiform.  The 
joints  8-10  of  the  antennae  increase  slightly  in  length,  but  the 
difference  is  not  very  obvious. 


NOIHASPIS  Lec. 
Meloe  parvuluH  Ilald.  differs  from  Meloe  by  the  elytra  not  being 
in  any  way  imbricate ;  the  scutellum  is  distinct,  triangular, 
rounded  behind,  and  projects  between  the  elytra,  which  are  con- 
nate for  about  one-third  of  their  length,  and  then  gradually 
diverge,  as  in  Meloe.  In  Henous  the  elytra  are  connate  almost 
to  the  tips.  This  genus  is,  therefore,  intermediate  between  the 
two  just  named,  but  more  nearly  allied  to  the  latter.

Pennsylvania  to  Texas.  The  difference  in  sculpture  of  the 
head  might  readily  cause  the  two  sexes  to  be  regarded  as  different 
species.  It  differs  essentially  from  E.  pennsylvanica  by  the  head 
being  less  densely  punctured  than  the  thorax,  and  by  both  being 
more  strongly  punctured  than  the  elytra.

New  Mexico  and  Arizona;  General  Pope  and  Dr.  Irwin, 
U.  S.  A.  This  form  is  allied  to  E.  maculata,  but  differs  by  the 
denuded  spots  being  much  larger  and  so  confluent  as  to  leave  a 
few  intervening  narrow  irregular  lines  clothed  with  gray  hair; 
by  the  naked  surface  being  smoother  and  less  opaque  on  the 
elytra,  and  really  polished  on  the  head  and  thorax ;  by  the  head

and  thorax  being  less  distinctly  channelled.     The  antennee  are 
rather  shorter,  and  slightly  less  slender. 

I  have  seen  no  males  belonging  to  this  form,  and  bat  one  of 
Lytta  conspersa  Lee. ;  but  have  observed  in  the  typical  specimens 
of  E.  maculata  that  the  denuded  spots  are  much  larger  in  the 
females  than  in  the  males,  and  therefore  conclude  that  the  differ- 
ences being  of  a  comparative  nature,  the  present  species,  as  well 
as  the  one  just  named,  should  be  regarded  as  races  of  j&.  maculata.

One  female  from  Kansas,  near  the  Rocky  Mountains;  Mr. 
Walsh  informs  ne  that  he  has  a  similar  one  from  Colorado  Ter- 
ritory. Allied  to  P.  engelmanni,  but  differs  by  the  color  of  the 
head,  by  the  thorax  being  less  elongate,  having  more  numerous 
impressed  punctures,  and  by  the  position  of  the  lateral  small  spots, 
both  of  which  are  on  the  inflexed  portion,  near  the  niiddhi,  the 
inner  or  upper  one  being  more  anterior,  and  the  outer  or  lower  one 
being  on  a  transverse  line  with  the  discoidnl  '*i)ot ;  in  P.  engel' 
manni  the  outer  one  is  anterior  to  the  f'  i.  '^  al  spot,  and  the 
inner  one  is  situated  on  the  apical  margin.  'V\w.  Fentellum  is  black, 
while  in  P.  enc/elmanni  it  is  in  whole  or  \v  :  nL  yellow  ;  the  elytra 
have  but  one  sub-basal  spot  on  each  sid(>,  near  the  suture;  the 
fasciform  spot  extends  from  the  second  fifth  to  the  fourth  fifth  of 
the  elytra  (attaining  as  in  P.  evcjdmamn  neither  the  side  margin 
nor  the  suture),  and  the  apical  black  margin  is  narrower.

the  tibiae  Dot  being  blue  at  base  and  tip,  and  by  the  tarsi  being 
yellow,  with  only  the  extremity  of  the  last  joint  and  the  claws 
blackish.  The  under  surface  in  both  is  clothed  with  long  soft 
erect  whitish  hairs. 

The  male  of  P.  sayi  has  the  last  ventral  segment  less  deeply 
excavated,  and  more  widely  bilobed,  and  the  anterior  tibiae  not 
so  much  compressed  above  the  middle,  and  much  less  concave  on

The  species  with  pubescent  elytra  are  closely  allied,  and  agree 
in  sexual  characters  ;  the  penultimate  ventral  segment  of  the  male 
is  very  slightly  emarginate,  and  the  last  joint  is  very  deeply  and 
acutely  emarginate,  but  not  excavated.  The  anterior  tibia;  are 
straight  in  both  sexes.  The  knees,  both  extremities  of  the  tibiae 
and  all  the  tarsi  are  blue  black  in  P.  tarsalis,  but  in  P.  senea 
and  filiformis  they  are  merely  blackish,  and  sometimes  scarcely 
obscure.

Rocky  Mountains,  from  the  Black  Hills  northward  into  the 
Hudson  Bay  Territory.  A  beautiful  species,  allied  to  L.  nuttaUi, 
but  diflfcring  by  the  color,  and  by  the  hind  trochanters  not  being 
armed  with  a  tooth  on  the  inner  edge.  The  middle  tibiaj  are 
curved,  and  the  outer  spur  of  the  hind  tibiaj  broad,  concave,  and 
somewhat  acute.  The  penultimate  ventral  seigment  in  the  male 
of  L.  niitlalli  is  broadly  emarginate  as  in  the  present  species, 
but  the  hind  trochanters  are  armed  with  an  acute  spine,  which 
in  the  female  becomes  a  prominent  angle.  In  L.  cyanipennis 
the  hind  trochanters  are  similarly  armed,  but  the  penultimate 
ventral  segment  is  acutely  emarginato.  L.  salicis  appears  to  be 
a  variety  of  L.  cyanipennis,  but  the  condition  of  the  specimens 
is  very  bad  and  renders  the  comparison  unsatisfactory.

Texas,  Mr.  Salle  and  Dr.  Horn ;  Lower  California,  Mr. 
XAntus.  This  species  differs  from  C.  ancjiistus  not  only  by  the 
small  smooth  spots  of  the  elytra,  but  by  the  foiiii  of  the  thorax, 
which  has  the  sides  straight,  merely  a  little  rounded  near  the 
apex.  In  C.  angustus  the  thorax  is  feebly  campanulate,  the 
sides  being  rounded  near  the  apex,  and  then  broadly  sinuate  to 
the  base.  The  pubescence  of  the  elytra  is  uniform  in  the  latter, 
while  in  G.  aspersus  longer  hairs  are  intermixed. 

It  is  interesting  that  C.  angushis,  described  by  me  from  a 
single  New  Mexican  specimen,  has  been  found  quite  abundantly 
by  Mr.  William  Couper,  near  Quebec,  Lower  Canado.  The 
sexual  characters  have  not  been  noticed  before,  and  are  as  foU 
lows:  Male  with  the  antenpae  longer  than  the  body,  flattened, 
tolerably  strongly  serrate ;  eyes  nearly  contiguous  at  the  vertex ; 
fifth  ventral  segment  deeply  and  broadly  eraarginatc,  sixth 
elongated,  emarginate  at  tip.  Female  with  the  antennae  scarcely 
two-thirds  the  length  of  the  body,  feebly  serrate ;  eyes  distant  at

One  specimen,  given  by  the  Rev.  D.  Ziegler,  as  found  in  York 
County,  Pa.  The  generic  characters  are  sufficiently  detailed  in 
the  work  above  cited.  I  will  merely  add  that,  although  the  head 
is  not  prolonged  into  a  beak,  I  have  associated  this  genus  with 
Mycterus  on  account  of  the  small  size  of  the  middle  coxro,  the 
dilatation  of  the  penultimate  tarsal  joint,  and  the  absence  of  the 
lateral  suture  of  the  prothorax.  The  short  1st  ventral  segment 
is  a  singular  character,  not  found  in  Mycterus,  nor  in  any  of  the 
neighboring  families  ;  the  2d  ventral  is  nearly  as  long  as  the  two 
following  united,  and  is  tumid  at  the  middle  with  the  anterior 
outline  convex  forwards ;  a  large  pale  yellow  spot  occupies  the 
whole  of  the  middle  portion ;  the  5th  ventral  is  not  shorter  than 
the  4th,  and  is  rounded  at  tip. 

I  regard  this  genus  a  connecting  form  from  Mycterus  to  Pythidae, 
though  the  full  development  of  its  relationships  must  depend  on 
the  discovery  of  other  specimens.

punctatia,  iuteratitiia  alternis  parce  uniaeriatim  punctatia  ;  aubtus  nigro- 
piceaa,  tibiia  taraisqne  piceo-teataceis,  antennis  piceo-testaceia,  articulis 
exteruis  piceia.     Long.  '12. 

One  specimen,  from  Kansas,  given  me  by  Dr.  S.  Lewis.  The 
thorax  is  narrower  and  more  convex  than  in  S.  virescens,  and 
the  punctures  are  more  distant,  agreeing  in  these  characters  with 
iS.  alternatus :  in  the  latter  the  thorax  is  scarcely  impressed,  and 
in  bo      species  the  legs  are  completely  blackish.

Maine  and  Canada ;  rare.  I  have  received  one  specimen  from 
Dr.  A.  S.  Packard,  and  another  from  Mr.  W.  Saunders  of  Lon- 
don, C.  W.  The  under  surface  with  the  legs  is  pale  piceous  in 
one,  but  nearly  black  in  the  other.
